Pre-owned Madden football games are everywhere. When you have a series that has been churning out a title every year for twenty years, there are a lot of discarded games to be peddled at flea markets or garage sales. With a massive supply built across almost every console for gaming generations now, the previous editions of Madden football have an almost nonexistent resell value. Outside of this mass production, there is one title that is not common and is one of a number of sports titles that hold value for collectors. John Madden Football Championship Edition was a rental store exclusive released in 1992 for the Sega Genesis and it is the Holy Grail of Madden Football games.
